    <p>I have an XML with invalid characters. LXML's XMLParser throws an exception on these invalid characters, but when I create XMLParser with <strong>recover=True</strong> option, it ignores the bad characters and works OK.</p> <p>My question is how can I set similar flag for lxml's iterparse function?</p> <p><strong>Reproduction:</strong></p> <p>The broken XML (/tmp/z.xml):</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;items&gt; &lt;item&gt; &lt;B&gt;Bad characters:&lt;/B&gt; &lt;/item&gt; &lt;/items&gt; </code></pre> <p><strong>NOTE:</strong> There are two ASCII characters #31 (0x1F) after "Bad characters:" string, which I could not copy-paste here.</p> <p>The parsing error of XMLParser:</p> <pre><code>fd = open('/tmp/z.xml') parser = etree.XMLParser() tree = etree.parse(fd, parser) Traceback (most recent call last): File "&lt;stdin&gt;", line 1, in &lt;module&gt; File "lxml.etree.pyx", line 2576, in lxml.etree.parse (src/lxml/lxml.etree.c:22796) File "parser.pxi", line 1488, in lxml.etree._parseDocument (src/lxml/lxml.etree.c:60390) File "parser.pxi", line 1518, in lxml.etree._parseFilelikeDocument (src/lxml/lxml.etree.c:60687) File "parser.pxi", line 1401, in lxml.etree._parseDocFromFilelike (src/lxml/lxml.etree.c:59658) File "parser.pxi", line 991, in lxml.etree._BaseParser._parseDocFromFilelike (src/lxml/lxml.etree.c:57303) File "parser.pxi", line 538, in lxml.etree._ParserContext._handleParseResultDoc (src/lxml/lxml.etree.c:53512) File "parser.pxi", line 624, in lxml.etree._handleParseResult (src/lxml/lxml.etree.c:54372) File "parser.pxi", line 564, in lxml.etree._raiseParseError (src/lxml/lxml.etree.c:53770) lxml.etree.XMLSyntaxError: PCDATA invalid Char value 31, line 4, column 21 </code></pre> <p>To ignore the bad characters I set <strong>recover=True</strong> and it works OK:</p> <pre><code>import lxml.etree as etree fd = open('/tmp/z.xml') parser = etree.XMLParser(recover=True) tree = etree.parse(fd, parser) etree.tostring(tree) # OUTPUT: &lt;items&gt;\n\t&lt;item&gt;\n\t\t&lt;B&gt;Bad characters:&lt;/B&gt;\n\t&lt;/item&gt;\n&lt;/items&gt;' </code></pre> <p>With iterparse I get the same error again, but how can I make it ignore the bad characters?</p> <pre><code>fd = open('/tmp/z.xml') it = etree.iterparse(fd, events=("start", "end")) for e in it: print e ...

    1. COhttp://comments.gmane.org/gmane.comp.python.lxml.devel/6235 read the last post. it seems that this is currently not possible with iterparse.

    2. COLooks like a duplicate of http://stackoverflow.com/q/14934854/407651, but that question has no accepted or upvoted answer. I suspect that the answer is what @pypat says.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
